Specification of Letters Patent No. 812, dated June 27, 1838.

To all whom'z't may concern:

Be it known that I, (JrEo. C. CHEsLEY, of Rockymount, in the county ofFranklin and State of Virginia, have invented a new and useful. machinefor pressing tobacco, cotton, oil, sugar, &c., or for crushing plasteror crushing and pressing apples or any other substance requiring hard ormoderate pressure by hand, steam, water, horse, or any other power equalthereto.

The construction of my invention is such, that by combination of leverpower, in the common lever in length and strength, and the power of thescrew and wedge I can press from one to any given number of hogsheads orboxes of tobacco, bales of cotton, &c., by hand, steam, horse, water orany other power equal thereto.

The frame consists of grooved uprights C, one sill A, one girder D, andas many cross sills B and top girders E (the one answering to the other)as there shall be drivers or stems M. Then there is a beam F runningparallel wit-h the sill A and with the girder D, thick or large in themiddle, tapering to the end to any size required.

This beam F has connected with it by ligature or hinge N, N an arm orarms Y, which are shouldered with tenon and which play up and down inthe grooves. Then to these arms are connected, a driver or stem, ordrivers or stems M, which are forced perpendicularly true, upon thesubstance, while the beam F moves obliquely from end to end alternately.Then the beam, carrying the arms and drivers, is worked by hand power alever is applied to each end of the beam with a loose band to be thrownoff or on as the pressure shall require, or for dispatch. WVhen quickoperation is required, the band is to be thrown on; but when hardpressure is needed, the band is thrown off, and theend of the lever ismade fast by means of a pin in the sword H, the lever resting upon theend of the beam F, yet made fast by means of a ligature or hinge N. Onthe application of hand power, the swords H, which are planted in theground, may be used, together with the wheel, crank, and

endless chain,v or in any of theknown ways, or means, by which handpower may be applied. Screw power may also beapplied, by fronting theframe of mymodel with the frame of a screw,with the screw in its frame,and by placing the si l A into the screw frame and so applying screwpower on each end of the beam, alternately, and by fastening the screwwith the end of the beam, the beam may be screwed up or let down one endat a time, yet thearms and drivers are carried perpendicularly true.

When this machine is worked by horse, steam, or water power, then acrank is used at each end of the beam, so as to play the beam obllquely,or from end to end, while the arms and drivers are carriedperpendicularly true.

The whole machine, with or without swords standing in house or field,may be made of wood, iron, or any other material, of any size, theframe, beam or beams, driver or drivers of any length, strength, width,

breadth, height, &c., and any given lever power, whether in lever,commonly so called,

that is in length and strength, whether in screw or wedge, may beapplied to the beam,

arms drivers or stems, the beam moving ob-x liquely, while thearms anddrivers or stems, with or without fixtures at the bottom for crushingand pressing, must go. perpendicu larly true, to affect the substanceplaced thereunder. WVhen the frame is widened, so that two or morebeams, carrying the arms and drivers, or stems, can be admitted, by

placing the beam to play obliquely, parallel with the sill and topgirder, then theends of the beams are yoked together witha beam, bar, orrod, made of any material, and the lever connected withthe beam, by bandor otherwise, is placed in the center of the beams, if only two beamsinthe frame, on

or across the yoke; the yoke being fastened to the lever, and yet theyoke lies in a rolling position, across the end of the beams while thelever, thus fixed at each endof the beams, can be worked as beforedescribed;

or if there" be three beams, then the lever is placed across the yoke,immediately at the end of the center beam, yet so fastened to the i beamand yoke with ligature or hinge, made of any material, as to bind theyoke and lever together, while theyoke lies in a r011 1 ing position,across the end of the beams v Geo/"j 0. 0665/07.
